Summer Flounder (Fluke)

Paralichthys dentatus. Prime water reaches Penobscot Bay in New England right now (53°F on the bottom). Fish it 26–71 ft down — that is where 55–52°F water sits off Penobscot Bay.

The strip is the water itself, coloured by temperature from the surface down to the 71 ft surveyed bottom at that spot — one band per RTOFS model level. The outlined stretch is where Summer Flounder (Fluke)'s temperature band (46–75°F) and the depth it holds actually overlap. That thickness is the number that matters: it is how much water you can work, not just whether the spot is warm enough somewhere. One model cycle, not a weekly archive — this holds still while the surface map scrubs.

How it's fished

Bucktail + strip bait drifted over sand near channel edges and structure.

"Fish it at" is where this species' temperature band and its holding depth overlap in the water column, from the RTOFS profile (13 levels, 0–300 m) — the depth to actually put a bait, not just the place. "Prime water" is the furthest sampled station on the 10-fathom lane whose seabed temperature sits inside this species' band. It is water, not a sighting report.
